Title
(EN) ELECTROSTATIC ADHESION OF DRY POWDERS TO MACRO FERTILIZERS
(FR) ADHÉRENCE ÉLECTROSTATIQUE DE POUDRES SÈCHES À DES MACRO-ENGRAIS
Abstract
(EN)
A method for electrostatically adhering an agricultural input powder to an agronomic carrier is described. A dry nutrient powder is electrostatically charged in a charging chamber which has a grounded metal component such that the electrostatically charged powder moves towards the metal component. The agronomic carrier is then passed by the charged powder such that the charged powder adheres to the carrier.
(FR)
L'invention concerne un procédé d'adhérence électrostatique d'une poudre de production agricole à un support agronomique. Une poudre nutritive sèche est chargée électrostatiquement dans une chambre de chargement pourvue d'un composant métallique mis à la terre de telle sorte que la poudre chargée électrostatiquement se déplace vers le composant métallique. La poudre chargée passe alors sur le support agronomique de telle manière que la poudre chargée adhère au support.
